Problem to uploading the firmware in px4

Hello everyone,
I am trying to upload the firmware in px4 flight controller
Use this command guide
make px4fmu-v3_default upload
After compiling this line

I waited upto 2 hours but nothing happened
I am using Ubuntu version 22.04.3 LTS (GNU/Linux x86_64)

I tried uploading through WSL2 before and faced the same issue. Ended up doing it through QGC.

One finicky thing to try is to unplug the USB and plug it back in.
